Cracked screen, dead battery, broken port: is your old laptop actually worth saving in 2026?

There's a moment every laptop owner recognises. The screen flickers, or the charger only works when the cable is wedged at 40 degrees, or the battery dies at 34%. And the immediate thought is: right, time for a new one.

Sometimes that's correct. Often it isn't. The gap between what a repair costs and what a replacement costs is wider than most people assume — and for a machine that's three or four years old and otherwise perfectly capable, a £90 fix can buy another two years of useful life.

Here's how the maths actually works out in the UK right now.

What common repairs really cost

Prices vary by region and by how easy the manufacturer made the machine to open, but these are realistic independent-shop ranges for 2026:

• Battery replacement: £70–£130 fitted with a genuine or OEM-grade pack, £35–£70 for a reputable compatible one. On most business laptops it's a ten-minute job; on glued-together ultrabooks it isn't.
• Screen replacement: £90–£180 for a standard 14-inch full HD panel, £180–£260 for a higher-resolution or touch panel, more for OLED. Cheap in parts terms, fiddly in labour terms.
• Keyboard: £40–£90. Some models only sell the keyboard as part of the whole top case, which pushes it towards the top of that range.
• Charging port: £50–£90 for a barrel jack that needs soldering, £30–£60 for a USB-C port on a separate board.
• Hinge repair: £60–£120, and worth doing early — a seized hinge is what cracks the screen and the chassis next.
• Thermal service (clean out, new paste): £45–£70, and the single most underrated repair on a four-year-old machine that sounds like a hairdryer.
• Liquid damage assessment: £30–£50, with no guarantee it's fixable. This is the one where we'd usually advise caution.
• Motherboard-level faults: frequently £150–£300 and often a false economy. Once you're at that number on a machine worth £250, stop.

A new laptop with 16GB of RAM and a 512GB SSD that's actually pleasant to use starts around £450–£650. A refurbished ex-corporate equivalent sits at £250–£400.

The 50% rule — and when to break it

A decent rule of thumb: repair makes sense when the quote is under half the cost of the replacement you'd otherwise buy, and the machine is under about six years old with parts still available.

But it's a rule of thumb, not a law. Break it when:

• The machine is unusually well built. A ThinkPad T14 or an EliteBook 840 with a fresh battery and cleaned fans will outlast a £400 supermarket special.
• You've already upgraded it. If you fitted 32GB of RAM and a 1TB SSD last year, that investment changes the calculation.
• The repair fixes the only real problem. A 2021 laptop with a cracked screen and a healthy battery is a very different proposition from one with a cracked screen, a swollen battery and a failing hinge.
• Replacement would mean downgrading. Going from a magnesium-chassis business machine to a plastic budget model to save £100 is rarely a win.

Break it the other way when the repair is chasing a fault you can't pin down — intermittent shutdowns, random freezes, USB ports that work when they feel like it. Two diagnostic fees and a motherboard quote is how a £120 repair becomes a £340 mistake.

Genuine parts versus compatible parts

This is where a lot of people get nervous, and mostly they needn't be — with exceptions.

Batteries are the exception. Buy genuine or a well-known OEM supplier. Some manufacturers run firmware checks that refuse to charge a third-party pack, and a cheap lithium cell in a laptop on your knees is not a risk worth taking for £40.

Screens are usually fine as compatible units, provided the shop matches the exact part number, resolution, connector type and finish. Ask to see the panel model before it goes in. A matte panel where you had glossy is a small but daily irritation.

Keyboards and chargers are generally fine from reputable suppliers. For chargers, stick to the brand's own or a known name like Anker or UGREEN with the right wattage and USB-C PD rating.

Hinges and chassis parts are worth sourcing genuine if you can, because pattern parts have a habit of failing the same way the original did.

Always ask for the old part back. It's your property, and it's useful evidence if something goes wrong later.

Students: buy time, not a whole new machine

If you're mid-course, a repair is usually the right call — not just financially but practically. A new laptop means migrating files, reinstalling software, re-authorising licences and losing a weekend you probably don't have. A battery swap or a screen replacement usually means a day or two without the machine.

Two things worth knowing: many universities run laptop loan schemes through the library, and most independent shops will prioritise a student with a deadline. Ask. Also, back up before you hand anything over — every shop says it, and every shop has a story about the customer who didn't.

If the machine is genuinely beyond saving, a refurbished ex-business laptop at £250–£350 will do everything a student needs and leaves budget for a decent bag and a spare charger.

Home workers and small offices: the downtime maths

For anyone earning from their laptop, the calculation shifts. A day of lost work can cost more than the repair itself, so speed and certainty matter more than squeezing the last £20 off a quote.

Small offices should think in batches. If you've got eight identical Latitudes or ThinkPads, keeping one spare chassis and a couple of charged batteries in a cupboard turns a crisis into a fifteen-minute swap. Standardising on one or two models also means the shop down the road can fix them quickly, and you're not hunting for obscure panels on a five-year-old consumer machine.

And don't forget the tax angle: repairs and replacements used wholly for work are generally allowable business expenses, so the real cost is lower than the sticker price.

Questions to ask before handing over your laptop

• Is the diagnosis free, and is it no-fix-no-fee?
• Is the quote fixed, or 'from'?
• Genuine, OEM or compatible parts — and which specifically?
• How long, and will you tell me if it turns out to be worse than expected?
• What's the warranty on the repair itself? Ninety days should be the minimum.
• Are you insured, and do you have a physical UK address?

If the answers are vague, walk. There are plenty of good independent repair shops in the UK, and a good one will happily talk you out of an uneconomic repair.

When to let go

Call it a day when the quote passes half the replacement cost, when the fault is on the motherboard, when the chassis is cracked in two places and the battery is swollen, or when the machine can't run a supported version of Windows. At that point, wipe your data properly, recycle it through a local WEEE point or a retailer's trade-in scheme, and put the money towards something that won't be back on the bench in March.

Keeping a laptop alive is usually the greener and cheaper choice. It just isn't always the sensible one — and knowing which is which is worth more than any single repair quote.
